Linus Torvalds 63de37476e chrome platform changes for v5.5
* CrOS EC / MFD / IIO
  - Contains tag-ib-chrome-mfd-iio-input-5.5, which is the first part of a
    series from Gwendal to refactor sensor code between MFD, CrOS EC, iio
    and input in order to add a new sensorhub driver and FIFO processing
 
 * Wilco EC:
  - Add support for Dell's USB PowerShare policy control, keyboard
    backlight LED driver, and a new test_event file.
  - Fixes use after free in wilco_ec's telemetry driver.
 
 * Misc:
  - bugfix in cros_usbpd_logger (missing destroy workqueue).

Linus Torvalds 388c645a33 SPDX fix for 5.5-rc1
Here is a single SPDX fixup for 5.5-rc1
 
 It resolves an issue where we had missed a few .h files with the
 auto-tagging scripts because they had "GPL" text in strings within the
 file themselves.  This single patch fixes up the issue and provides the
 proper SPDX tags at the top of them as needed.
 
 This patch has been in linux-next for many many weeks now with no
 reported issues.

Linus Torvalds 537bd0a159 TTY/Serial patches for 5.5-rc1
Here is the "big" tty and serial driver patches for 5.5-rc1.  It's a bit
 later in the merge window than normal as I wanted to make sure some
 last-minute patches applied to it were all sane.  They seem to be :)
 
 There's a lot of little stuff in here, for the tty core, and for lots of
 serial drivers:
 	- reverts of uartlite serial driver patches that were wrong
 	- msm-serial driver fixes
 	- serial core updates and fixes
 	- tty core fixes
 	- serial driver dma mapping api changes
 	- lots of other tiny fixes and updates for serial drivers
 
 All of these have been in linux-next for a while with no reported

     before the driver probe (Remi Pommarel)

   - Fix Aardvark issues with Root Control reads and writes (Remi
     Pommarel)

Pull timer updates from Ingo Molnar:
 "The main changes in the timer code in this cycle were:

   - Clockevent updates:

      - timer-of framework cleanups. (Geert Uytterhoeven)

      - Use timer-of for the renesas-ostm and the device name to prevent
        name collision in case of multiple timers. (Geert Uytterhoeven)

      - Check if there is an error after calling of_clk_get in asm9260
        (Chuhong Yuan)

   - ABI fix: Zero out high order bits of nanoseconds on compat
     syscalls. This got broken a year ago, with apparently no side
     effects so far.

     Since the kernel would use random data otherwise I don't think we'd
     have other options but to fix the bug, even if there was a side
     effect to applications (Dmitry Safonov)

   - Optimize ns_to_timespec64() on 32-bit systems: move away from
     div_s64_rem() which can be slow, to div_u64_rem() which is faster
     (Arnd Bergmann)

   - Annotate KCSAN-reported false positive data races in
     hrtimer_is_queued() users by moving timer->state handling over to
     the READ_ONCE()/WRITE_ONCE() APIs. This documents these accesses
     (Eric Dumazet)

   - Misc cleanups and small fixes"

[ I undid the "ABI fix" and updated the comments instead. The reason
  there were apparently no side effects is that the fix was a no-op.

  The updated comment is to say _why_ it was a no-op.    - Linus ]

  work->irq_work.flags into an atomic variable and then convert the
  complex (and buggy) atomic_cmpxchg() loop in irq_work_claim() into a
  much simpler atomic_fetch_or() call.

Pull XFS updates from Darrick Wong:
 "For this release, we changed quite a few things.

  Highlights:

   - Fixed some long tail latency problems in the block allocator

   - Removed some long deprecated (and for the past several years no-op)
     mount options and ioctls

   - Strengthened the extended attribute and directory verifiers

   - Audited and fixed all the places where we could return EFSCORRUPTED
     without logging anything

   - Refactored the old SGI space allocation ioctls to make the
     equivalent fallocate calls

   - Fixed a race between fallocate and directio

   - Fixed an integer overflow when files have more than a few
     billion(!) extents

   - Fixed a longstanding bug where quota accounting could be incorrect
     when performing unwritten extent conversion on a freshly mounted fs

   - Fixed various complaints in scrub about soft lockups and
     unresponsiveness to signals

   - De-vtable'd the directory handling code, which should make it
     faster

   - Converted to the new mount api, for better or for worse

   - Cleaned up some memory leaks

  and quite a lot of other smaller fixes and cleanups.

  A more detailed summary:

   - Fill out the build string

   - Prevent inode fork extent count overflows

   - Refactor the allocator to reduce long tail latency

   - Rework incore log locking a little to reduce spinning

   - Break up the xfs_iomap_begin functions into smaller more cohesive

Linus Torvalds 937d6eefc7 Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

 	  for imlementing the DMA-API. This gets rid of quite some code
 	  in the driver itself, but also has some potential for
 	  regressions (non are known at the moment).
 
 	- Support for the Qualcomm SMMUv2 implementation in the SDM845

Merge tag 'for-linus-20191129' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "I wasn't going to send this one off so soon, but unfortunately one of
  the fixes from the previous pull broke the build on some archs. So I'm
  sending this sooner rather than later. This contains:

   - Add highmem.h include for io_uring, because of the kmap() additions
     from last round. For some reason the build bot didn't spot this
     even though it sat for days.

   - Three minor ';' removals

   - Add support for the Beurer CD-on-a-chip device

   - Make io_uring work on MMU-less archs"

Linus Torvalds 99a0d9f5e8 This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
 
 - Expose pull up/down flags for the GPIO character device to
   userspace. After clear input from the RaspberryPi and Beagle
   communities, it has been established that prototyping,
   industrial automation and make communities strongly need
   this feature, and as we want people to use the character
   device, we have implemented the simple pull up/down
   interface for GPIO lines. This means we can specify that
   a (chip-specific) pull up/down resistor can be enabled,
   but does not offer fine-grained control such as cases
   where the resistance of the same pull resistor can be
   controlled (yet).
 
 - Introduce devm_fwnode_gpiod_get_index() and start to phase out
   the old symbol devm_fwnode_get_index_gpiod_from_child().
 
 - A bit of documentation clean-up work.
 
 - Introduce a define for GPIO line directions and deploy it
   in all GPIO drivers in the drivers/gpio directory.
 
 - Add a special callback to populate pin ranges when
   cooperating with the pin control subsystem and registering
   ranges as part of adding a gpiolib driver and a
   gpio_irq_chip driver at the same time. This is also
   deployed in the Intel Merrifield driver.
 
 New drivers:
 
 - RDA Micro GPIO controller.
 
 - XGS-iproc GPIO driver.
 
 Driver improvements:
 
 - Wake event and debounce support on the Tegra 186 driver.
 
 - Finalize the Aspeed SGPIO driver.
 
 - MPC8xxx uses a normal IRQ handler rather than a chained
   handler.
